Another Reagan heads for Mars and we'll hear it working this week on planetary radio. Welcome, I'm Matt Kaplan of of the Planetary Society, with more of a humid adventure across our

solar system and beyond.

Rogerians heads the Super Cam instrument on the Perseverance Rover. Its laser will heat up our search for past life,

while its microphone will finally let us listen to the wind blow on the red planet.

Our great conversation is coming right up.

SuperCam's big eyes up on top of the perseverance mast sharing that space with the

Stereovision Mass Cam Z. We'll hear your great attempts to turn that name into a

NASA acronym in today's What's Up, along with Bruce's guide to the night sky.

Shining brightly in that sky is mighty Jupiter. A beautiful

new view of the planet tops the August 7 edition of the Down Lake, which also includes these

headlines.

Mars once had liquid water on its surface,

but there may have been less than some hoped.

A new study says most of the water

may have been hidden under the surface in giant ice sheets.

This could actually be good news for possible life, as it might have been better protected

from radiation and other challenges. Back to Jupiter for a story

we'll take a deep dive into next week. According to a new study, the big bully may

have prevented the formation of more worlds in our sun's habitable zone.

Of course, we knew the early solar system was a dangerous place, what with big chunks of

planet forming material slamming into everything.

China's U22 has found more evidence of this below the moon's surface.
